How does a ReplicaSet differ from a Deployment in Kubernetes?

ReplicaSet and Deployment are Kubernetes objects related to pod management but have different tasks:

• ReplicaSet is responsible for maintaining a specified number of identical pods. If a pod crashes, the ReplicaSet will create a new one to maintain the desired count.

• Deployment is a higher-level abstraction that manages ReplicaSets. Deployment allows for updates (rollout), rollbacks, scaling, and managing update strategies for pods.

In simpler terms, Deployment uses ReplicaSet to manage the lifecycle of pods, providing convenient mechanisms for updates and version control of applications.
